Gout flares are painful inflammatory episodes caused by crystals of monosodium urate (MSU) that result from excess serum uric acid (sUA). In three Phase 2 studies in gout patients arhalofenate was shown to reduce the incidence and duration of flares while simultaneously lowering sUA. If confirmed in additional clinical studies, arhalofenate’s dual acting profile would be unique since all other urate lowering therapies paradoxically increase flares as they lower sUA over the first 6 to 12 months of treatment. Increased flares lead many patients to stop or avoid treatment leading to progression of disease with pain and suffering, erosion of joint structure and functionality, lost time from work, and increased healthcare costs. | $8.6M | Series E | Nov 05, 2009 |  |
